The 4100 Series shocks introduce high performance monotube technology at prices competitive with twin tube insert coilover kits. They include purpose built strut and shock bodies, shortened from stock lengths. All kits come with anodized aluminum adjusters that stay on the shock; no need to keep your pockets full of tools to make quick adjustments.

The 5100 Series shock absorbers utilise inverted / upside down technology. The inverted design is race proven technology and produces an extremley strong damper, providing better suspension geometry under heavy lateral and braking loads as seen in a road and track environment.

The 5100 Series shock absorbers give your car a better performance than the standard twin tube design. With the 5100 Series suspension you can adjust rebound with one knob. The adjust platform allows you to adjust the ride height of your car. AST suspension shock bodies are specially designed to keep maximum stroke, even with a lower ride height.

The 5200 Series are 2-way adjustable shock absorbers which are based upon competition 3-way adjustable shock absorbers. The 5200 shock absorbers are adjustable in compression and rebound.

The design of the compression adjuster is an evolution of the compression adjuster we provided for the American Grand-Am series for the last few years. The 5200 shock absorbers were designed to achieve a quick and easy set up, allowing separate adjustment of compression and rebound.

In the 5200 Series AST uses an external canister.
